The Reds had taken a first-half lead, as we had done at Burnley in midweek, with a goal after 21 minutes by Jadon Sancho.
But, once again, a lead at the break was rubbed out and two points were lost in the race for a top-four place as Saints equalised two minutes after the interval through Che Adams.
It was an exciting spectacle but United couldn't find a winner, Harry Maguire coming closest, and the match ended 1-1.
FIRST HALF - SANCHO DRAWS FIRST BLOOD
There were some frantic and entertaining opening exchanges with both goals under pressure.
